Means for limiting the forward and backward travel of said element 11 upon said support 17 are provided by members 20 and 2l, the member 21 being provided withan arcuate groove 22 in which is arranged to travel a pin 23 provided on said lever 18, whereby one end of said lever 18 during the oscillation thereof is caused to move in the path of an arc while the other end thereof is caused to move in a rectilinear line. The purpose of this provision is to maintain the pressure of said lever 18 always directly in line with the central axis of the fulcruml and to reduce to a minimum any frictional movement of the lever relative to the fulcrum unit 15; This is especially necessary where heavy pressure is exercised upon the lever. Y The head member 12, which constitutes preferably an integral part of the element 11 is provided with an extension 24, which normally is disposed within an opening 25 in the limiting member 20. rhus, when the lever 18 is depressed and caused to rotate about the fulcrum unit 15 and to one side of the-vertical central plane thereof, the element l1 is propelled forward against the limitingmember 20, and the extension 2A is projected beyond said member 20, as shown in dotted lines Fig. l.

Upon removal of the pressure from one end of said lever 18, the spring' 19 operates to rotate the lever about said fulcrum 15 to the other side of the central vertical plane thereof, thereby causing the element 11 to be moved backward and the extension 24; to be retracted.

Means for limiting the inclination of the lever 18 relative to the vertical central plane of the f-ulcrum 15, and thereby regulating the speed of travel of the element l1 andthe force incidentthereto, may be provided in a variety of ways or by any number of devices.

One instance of an effective means for so limiting the angularity of the lever 18 is illustrated in Fig. l and'comprises a plurality of holes 26 for the reception of pins or stop members 27, which Vare arranged to be disposed within the path of travel of the lever 18'Y and which confine the operation of said lever to definite limits in accorda-nce with the amount of force that it is desired to produce.

It will be obvious that the force produced by the reciprocation of said element may be employed in a. number of ways to produce or control mechanisms, and it will also be arparent that the device as represented and described is merely an eXemplilication of a form of embodiment of the invention, the essence of which is related in the accompanying claims.

What I claim, is:

1. A support, an element adapted to be driven to and fro on said support and having anti-friction means for rolling engagement with said support, anti-friction means in engagement with said lirst named anti-friction means, and a lever arranged'to fulcrum upon said last named anti-friction means thereby to propel `said element to and fro upon said support.

2. A support, an element adapted to be driven to and fr0 on said support, and having anti-friction means for rolling engagel ment with said support, anti-friction means superposed on said first-named anti-friction means, and a lever having rolling engagement with and fulcruming on said last named anti-friction means to propel said element to and fro upon said support.

3. A mechanical movement comprising a thrust member having centrally thereof a plurality of superposed revoluble units, a support for said thrust member, an inclined plane in engagement with one of said revoluble units, means to vary the inclination of said plane to impely said member Vforward and backward and means to limit the tra-vel of said member.

el. A mechanical movement comprising au element arranged to be driven, a support for same, a plurality of contacting revoluble units in said element, a plane in contact with one of said units and 'arrangedfor inclination relatively thereto, to propel said element forward and backward, and means to limit the degree of inclination of said plane relative to said revoluble unit to regulate the speed of travel of said element. n

5. A mechanical movement comprisingan element arranged to be driven, a support for same, anti-friction means in said element, a plane in contact with said anti-friction means and arranged for inclination relatively thereto to propel said element to and fro upon `said supportand means to limit the degree of inclination of said plane relative to said antifriction means to regulate the speed of movement of said element.

6. A mechanicalmovement comprising a support, a driven element on said'support,a plurality of anti-friction means associated with said driven element, and means for eX- erting pressureon one of said anti-friction means and laterally of the central plane therethrough to cause the other of said antifriction means to reciprocate said driven element.

7. A mechanical movement comprising a support,a thrust member thereon, a lever arranged to fulcrum upon said thrust member thereby a reciprocate same upon said support, and yielding meansacting upon said lever to maintain samer in Contact with said thrust member. j

8. A mechanical movement comprising a support, a thrust member on said support, superposed anti-friction units associated with said thrust member, one of said units arranged or rolling contact With said support, and means arranged to fulcrum upon the other of said units to propel said thrust member to and fro upon said support. c

9. A support, a driven element on said support having contacting revoluble units and a driving element arranged to fulcrum upon s one of said units to transfer its rolling motion to the other yof said units and thereby propel said driven element to and fro upon said support. p

10. A mechanical movement comprising a support, a driven element on said support, means associated With said Idriven element to propel same, and means tiltable with respect to the vertical axis of said propelling means to reciprocate said driven element upon said support. p
